Face in the News: Foreign policy dominates the discussion

WASHINGTON (CBS News) - Foreign policy dominated "Face The Nation" on Sunday, with lawmakers weighing in on the unraveling crisis in Iraq and the trial of Benghazi suspect Ahmed Abu Khatallah.

Rep. Michael McCaul, R-Texas, chairman of the House Committee on Homeland Security, slammed the Obama administration for bringing Khatallah to Washington, D.C., to face trial. He said Khatallah, arrested in Libya by U.S. special forces earlier this month, should be sent to the Guantanamo Bay detention camp.

"We have brought a criminal terrorist and given him due process under our Constitution here in the United States in the national's capital," the Texas Republican said. "I do not think that is the right approach in prosecuting the war on terrorism."

McCaul's comments were picked up by The Hill, Politico and CNN.

Sens. Joe Manchin, D-W.Va., and John Barrasso, R-Wyo., spoke about the deteriorating situation in Iraq. Muslims extremists from the group ISIS, who gained strength and numbers fighting in neighboring Syria, recently overran Iraqi forces in several key cities and on Sunday declared an Islamic caliphate.

Manchin broke with his party and said he opposes President Obama's request for $500 million to help moderate elements among the Syrian rebels, a move to counter the influence of ISIS in the region.

"If military might or money would have solved that problem in that part of the world, and we could have made it better, we'd have done it by now," Manchin said, adding that the region is destined for sectarian civil strife. These comments were covered by the Washington Post and the Los Angeles Times.

Barrasso said ISIS is a "direct threat" to the U.S. and has become the "richest, most powerful and most savage group of terrorists in the history of mankind," even outflanking al Qaeda, which organized 9/11. These comments were picked up by the Washington Post, Politico, Newsmax and the Fiscal Times.

Back at home, immigration reform is again in the news: A surge of young immigrants are illegally flowing across the U.S. border with Mexico, creating what many have called an urgent humanitarian crisis.

Traffickers and smugglers are telling desperate Latin American families that children who make it across the border will be allowed to stay, a claim the Obama administration strongly denies. McCaul said the problem is so severe in his home state of Texas that there are now refugee camps for immigrants.

McCaul's comments on immigration were covered by the Los Angeles Times, The Hill and Newsmax.
